MAYBE

Problem:
 f(true(),xs) -> f(eq(s(length(xs)),length(cons(a(),xs))),append(xs,cons(a(),nil())))
 length(nil()) -> 0()
 length(cons(x,xs)) -> s(length(xs))
 eq(0(),0()) -> true()
 eq(s(x),0()) -> false()
 eq(0(),s(y)) -> false()
 eq(s(x),s(y)) -> eq(x,y)
 append(nil(),ys) -> ys
 append(cons(x,xs),ys) -> cons(x,append(xs,ys))
